Massively Multiplayer Online Role Playing Game

Massively Multiplayer Online Role Playing Games (MMORPGs for short) are a genre of video and computer games that involve many players logging into a server that is usually owned by the company that develops or publishes the game and playing in a virtual world. This world is persistent. (It exists even you aren't playing)

MMORPGs almost always charge a monthly fee; this is necessary to maintain the expensive servers used, to hire support staff, and to develop new content. While the cost of developing a MMORPG is high the potential profit can be extraordinary as well. Two notable MMORPGs are Everquest and World of Warcraft.
